Hi, im kind new to xoops, my site have been working fine in the las 2 weeks but just 2 days ago i change a few things and now i cant log in as administrator I only see a "User" login interface but i cant find the admin Login interface ... and if i tray to log in in to the user interface with my admin username and pass it telsme "Incorrect Login!!!". what should i do ?

.
Are we talking about XOOPS 2.xxxx here?

If so there is only one login. No difference between admin and user login window. So if it tells you 'login incorrect' it means that either your database entry for the admin is corrupted or that you indeed got the wrong password.

What happens when you click on 'lost password' and have it mailed to you? Is it really the one you are trying to use?

Have you railed out the usual suspects like CapsLock, NumLock, leading or trailing spaces ...?
(have to ask because i work in it support and you wouldn´t believe how many case we have stuff like this )
